Magnification produced by a convex mirror is `1/3`, then distance of the object from mirror is

State whether the following statements are True or false: The magnification produced by a convex mirror is positive or negative depending on the object distance.

A convex mirror of focal elongth f produces an image magnified m times.The distance of the object from mirror is

An object is placed on the principal axis of a convex mirror of focal length 15 cm. If the distance of the object from the mirror is 30 cm, where should a plane mirror be placed such that the images produced by the two mirrors coincide?

Answer the following questions: Express the magnification produced by a spherical mirror in terms of the focal length of the mirror and the object distance.

The focal length of a concave mirror is f and the distance of the object from the principal focus is x . The magnification of the image produced is
